Good-Lite LEA Numbers Low Contrast Chart for Illuminated Cabinet

The Good-Lite LEA Numbers Low Contrast Chart is a special way to measure visual acuity, assessing how well eyes function in low light situations and/or being able to distinguish items from similarly colored or shaded backgrounds. Testing is identical to the measurement of visual acuity at high contrast level. The 2.5% test is the most practical test in clinical use.

This chart is to be used in an ESV1200 or Model A+ illuminated cabinet.
